METALLIC ROOFING-SHlNGLE.

SPECIPICATlION forming part of nettem Patent are. 303,921, dated Augilst19, 1884.

Application filed May 7, 1884. (No moth-Ll To all whom it may concern:

Beitknown that I, WILLIAM H. CUsAoK,'a

' citizen of the United States, residing at Nashville, in the oonnty ofDavidson and State of Tennessee, have invented certain new and usefulImprovements in Metallic Roofing-Shingles, of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention relates to a roof composed of sheetmeta-l shingles; and thenovelty consists in the construct-ion,arrangement, and adaptationofparts, as will be more fully hereinafter set forth, and specificallypointed out in the claims.

The essential object of the invention is to produce a. roof which shallbe water-tight and externally fireeprooflthe saidroof hei ngfo rmed ofsheet-metal shingles, which can be convento the next one in the order oflaying them,-

but in all such instances known to me either the blank has been cut togreatly waste the material or theinterlocking parts have been so formedas to render the completed roof liable to leak.

This invention contemplates a great saving of the materialand an elementof safety from leakage at thc joints by reason of the simplicity inwhich the cuts in the blank are made, and contemplates also an elementof conyenience in providing a securing-lug at the top corner oftheshingle, so that the weight or gravity of the shingle will not tendto sag it out of place. i

I have illustrated and will describe the in vention as embodied in asquare shingle or series of them; but it will be'obvions that anyrectangular form may be used.

The invention is illustrated .in the accompanying drawings, which form apart of this specification, and in which- Figure 1 is a plan view of ablank forelsirr gle shingle, showing at three of the corners a' smallpiece cut out or cntaway, and at the right upper corner two outs madefarther from the corner point, the dotted lines showingthe folding orbending points. Fig. 2 is a plan view of the same blank folded, theright and upper edges 'being folded in one direction to leave thesecuring log or car extended, and the other edges being folded back inthe oppositedirection. embodying my invention, one of the shingleshaving a struck-up ornamentation or floora slight saving in the materialor a simple out which improves the adaptation of lhe shingle with itsfellows is important in the art.

To bring my invention out clearly, I will describe the construction .andadvantages of. my shingles in the order oft-he steps taken in theirmanufacture and application to form a complete roof.

deterring to the drawings, in which similar letters of referenceindicate like parts in all the figures, A designates one of a series ofsquare onicetangular metal sheets of any prc- -fcrrcd dimensions. Thissheet A, by proper machinery, is ornamented and strengthened by astruck-up figure, as u, in anydcsirablc manner, the figures, of course,all being alike so that the several sheets may pack closely together.Either at the same time or subsequently, by proper machinery, a smallsquare section is cut out of three of the corners, as seenat I), and twocnts, I), are made in the remaining corner at such distance from thepoint 0 as to leave a neck, (I, and a perforated securing-lug, c, intactwith the blank. These cuts, which may extend inward one-half inch, {moreor less,) form interlocking-or engaging lips, those markcdff being bentforward and over and back to lie close against the face of the shingle,and those marked f 'f being bent in the opposite direction, the lips fof one shingle being adapted to engage the lips f of the adiacentshingle when the roof is being Fig. 3 is a section of a roof laid. Thispart of the invention is fully'illustrated in Figs. 1 and 2, and itwillbe observedthat each locking-lip comprises the outer edge of the blank,.so that only the small portions 5 of the three corners of-each blankare cut "away, and that one of the lips f overlapsthe other lip fatth'c'point adjacent tothe lug 0. These features areiinportant, aswillbe shown, not only in the fact that but a very small portionof theblank is cut to waste, but that very little labor is necessary toproduce the shingle in the form shown inlFi'g. 2, The

feature of the oneLlip-f overlapping the other adjacent tothe lug e isalso important for the g 5 reason that this constitutes the-uppercorner,

.the securing-corner of the shingle in the process of-layingthen1,"andis the point where leakage is most liable to occur. It willalso be v observed that atthe three corners designated adjacentlip, andto set forth clearly the fiinctions of theselips I will refer toFigs.'3,4, and 5,

i nwhich four adjacent shinglesare given nu merals 1,' 2,3, and'4,as-designating-synibols. Shingle 1 having been secured totheroofboards}shingle2 is brought into position, and as its lip f is brought into.engagement with I the lip f ofthe shingle 1, its upper left-hand lip, f,passes under the other or overlapping lip of shingle 1 to form aconsiderable lap at that point. Then when shingle 3 is brought intoposition this lap-joint formed by the lip f of shingle 2 and the lip fof shingle 1 is thus forming three complete imperforate sur faces ateach corner, with every adjacent part overlapping and'breaking joints.\Vhen shingle t-is brought into position, it gives an im,

' perforate cover over the joints, as 'show n in.

Fig. 3. The'complctcness of this joint-is due to the overlapping 'lipsan d'to their arrangement relatively to each other.

I deem the fastening lug or car. located at the upper corner and havingthe relation shown to the locking-lips important. It isformed by the outwhich makes thelip ff, and

is thus brought into the position shown, wherein, as soon as the nail is-driven,- after the'interlocking lips have been properly engaged,

' so the gravity of the shingle tends to hold it by b each lip foldssquarely upon the other completely. covered by the lip f of shingle 3,-

against displacement, while if located at theright or left cornerthegravity would tend to disengage .the look. I also deem this con-'struction of the shingle important for the rea-' son that veach nail orscrew used. to lock 21. shingle in place, by reason ofthe arrangement ofinterlocking-lips, is equivalenttoe fastening at eight points, as willlee-obvious to those skilled inthe art. At t, I illustrate folded piecesof sheet metal, with perforations i, which are used at each upper sidebf each shingle to secure the same to the sheathingboards. These piecest on the lip nearest the roof-boards serve efficiently to hold theshingle in place. Having thus, described my invention, what I. claim,and desire to secure by Letters Patent,

1. A roofing.- shingle formed of a single sheet of metal byeightstraight'cnts, with intcrlockingf,li1 s.and a securingdug, e, as and forthe purpose setforthl' g 2. Theroofing-shingledescribed, having theoverlapping and interlocking lipsff andf-f by 'the straight cuts as set3. A roofing-shingle' forxned of sheet -metal, and having straight cutsmade in each sideto cut away parts, asat b, and having cuts; as '8o' 1),at a greater distance from the corner cl to form neckd and lug e, as setforth.

4. A series of roofing-shingles, each formed 4 of .a single sheet ofmetal, andhaving strength ening struck-up figures a, each fornied by 55straight cuts and bending into overlapping and interlocking lips ff andf f. and lug e, r and the whole adapted to serve together, as and forthe purposes set forth.

5. In combination with the shingles A,'havco 'ing lipsfand f, and havinglug e, the lo'clc ing-pieces i,-perforated and folded, as shown,

and the whole adapted to-beused asset forth.

In testimony whereof- I aiiix my signature in presence of two witnesses.WILLIAM .H} oUsAoK.
